Abstract Vectorial optical fields (VOFs) exhibiting arbitrarily designed wavefronts and polarization distributions are highly desired in photonics. However, current methods to generate them either require complicated setups or exhibit limited functionalities, which is unfavorable for integration-optics applications. Here, we propose a generic approach efficiently arbitrary VOFs based on metasurfaces full-matrix yet inhomogeneous Jones-matrix distributions. We illustrate our strategy with...

Abstract Although metasurfaces have shown great potential for manipulating light, most previously realized meta-devices suffer from uncontrolled angular dispersions, making them unfavorable many applications. Here, we propose a general strategy to realize optical with desired dispersions based on carefully controlling both the near-field couplings between meta-atoms and radiation pattern of single meta-atom. Utilizing such strategy, experimentally demonstrate series predesigned including two...

Relying on both resonant Pancharatnam–Berry mechanisms, our meta-device can couple circularly polarized surface plasmon, which then focused into spot placed with target device. We experimentally...
Abstract A device that can couple propagating light into surface plasmon polaritons (SPPs) focused a small region is highly desired for on‐chip photonics applications (e.g., energy‐harvesting, sensing, etc.). However, current technologies suffer from large footprint, low working efficiency, and insufficient light‐manipulation freedom. Here, generic approach designing plasmonic lenses to generate predesigned vector SPP vortices with high efficiencies established. Constructed set of meta‐atoms...
